<p>This invention comprises reinforced industrial vaults (400) with segmented knock-outs (424) having a variety of shapes and orientations. This invention also comprises vaults having cast-in cable racks (452). The cable racks can be electrically connected to the reinforcing elements (600) during manufacture, providing electrical grounding of electronic equipment placed within the vault. Cable channels can be installed at desired locations by selecting a knock-out, removing the knock-out, and installing a terminator plate (1116, 1118, 1119) having cable conduits (1124, 1126, 1127). Cable conduits can have diaphragms (1132) that can be removed to provide additional choices for locating cable channels. Cable channels can be provided in a vault in the field, even if the vault has been already installed.</p> |
